Investigating Particle Breakage Behaviour Under Various Contact Topologies Using µfe Approach

Abstract To have a better understanding of the contact topology and how it contributes to the breakage behaviour of irregular particles, this study adapts a micro finite element (µFE) model to simulate the single particle breakage under point loading. The model is first validated against an experimental test and then used for investigating the influence of contact area on breakage behaviour by altering the radius of contact curvature. The results are analysed in terms of load-strain curve, fracture pattern and contact area.
